As it is a Hellenic (Greek) name, and also my name, the correct pronunciation of it is: Ka-llyi-oh-pyi. Some other linguists however relate it to beautiful eyes from the present perfect tense of the verb "see" (simple present: orao (type A), oro (type B), opopa (present perfect) and opthalmos which is the eye in Ancient Hellenic) and some others to beautiful face from "opsis".
